Here are the limits on the size of the data that's copied into a storage account. Make sure the data you upload conforms to these limits. For the most up-to-date information on these limits, see Scalability and performance targets for Blob storage and Azure Files scalability and performance targets.
| Size of data copied into Azure storage account | Default limit |
|---|---|
| Block blob and page blob | Maximum limit is the same as the Storage limit defined for Azure Subscription and it includes data from all the sources including Data Box. |
| Azure Files | Data Box supports Azure premium file shares, which allow a total of 100 TiB for all shares in the storage account. Maximum usable capacity is slightly less because of the space that copy logs and audit logs use. A minimum 100 GiB each is reserved for the copy log and audit log. For more information, see Audit logs for Azure Data Box, Azure Data Box Heavy. All folders under StorageAccount_AzFile must follow this limit. For more information, see Create an Azure file share. |
